AF Res BW
Sets the resolution bandwidth of the spectrum converted from the demodulated
waveform through an FFT. The spectrum is displayed in the AF spectrum window.
The shape of the filter is Gaussian.
Remote
Command
[:SENSe]:LORA:AFSPectrum:BANDwidth <freq>
[:SENSe]:LORA:AFSPectrum:BANDwidth?
Example
:LORA:AFSP:BAND 1 kHz
:LORA:AFSP:BAND?
Notes Only certain discrete resolution bandwidths are available. For numeric entries, the input will be rounded
up to the nearest possible RBW
Couplings
When the AF resolution bandwidth is set to auto, the resolution bandwidth is automatically calculated
according to the span with an approximate ratio of AF span/RBW being 106:1.The value should not
exceed 3 MHz
Preset 180 Hz
State Saved Saved in instrument state
Min 1 Hz
Max 8 MHz
Annotation A “#” mark appears before “AF Res BW” in the annotation when it is switched from Auto to Manual
